\\Anp'lication filed March 14, 1904. Serial No. 198.038.

`is cast in a revolving mold, the object of my invention being yto provide a simple and efficient casting apparatus of this character in which relatively small ingots can be readily produced and. in which the character of the ingot can be varied by varying the speed of rotation of the mold. f

In the accompanying draw' gs, Figure 1 is a side elevation, partlyin sectign, of an ingotcasting mold constructed in accordance with my invention. Fig. 2 is a transverse section of the same on the line w w; and Figs. 3, 4, 5,

- l and 6 are respectively sectional-plans on the lines a b, c d, ef, and g h, Fig. 2.

The machinel constituting the subject of my present invention has a rigid base or foundation 1, from which rise two vertical posts or columns 2 2, rigidly connected and braced by suitable transverse bars 3 and 4 and also stayed, if desired,.by bars 5, leading to' any adjacent fixed structure.

The cross-bar 3 is provided with a bearing for a vertical shaft 6, which is likewise adapted to a suitable step-bearing in 4the base or foundation bar 1.of the structure, this shaft being provided with a grooved pulley. 7 or other suitable means whereby it may receive power in order to impart to it any desired speed of rotation.A The upper end of the shaft carries a head 8, provided with projecting lugs 9, which are adapted to engage with lugs 10 on the bottom of the mold 11, the latter beiiig thereby supported vertically upon the head 8 and caused to rotate therewith.

The vertical posts or columns 2 serve as guides for a sliding cross-head 12, to which vertical reciprocating movement can be impart-ed by means of a forked lever or pair of levers 13, hung to a rod 14, which is secured to or forms part of the lower one of a pair of bars 15 and 16, the up er one of which is secured to and depends om the top cross-bar 4 of the rigid frame. Each bar is provided with a series of openings 17 for the reception justed vertically on the bar 16, .so asv to provide for the use of molds 11 of different heights. The sliding cross-head 12 is adapte, ed to bear upon the cap 1910i the mold 11,

-which cap has a depending portion or plug fitting with reasonable snugness to the interior of the mold. The rotation of the cap 19 with the mold may be insured by providing said mold with lugs 20, adapted to recesses in the cap or in any other suitable way.

Mounted upon the cross-head 12 is a hopper 21, which has a downwardly-projecting spout 22 passing through the cross-head and. a

of bolts 18, whereby the bar 15 can be ad@ so through a central opening in the moldca 19, as shown in Fig. 2. V n the operation of the device the crosshead 12, with its hopper, is first raised so that the empty mold can be placed upon the head 8. The mold, with the cap 19 uponit, being properly located, the-cross-head 12 is lowered until the projecting spout 22 of the hopper passes through the central opening of the mold-cap, as shown in Fig. 2, whereupon ro'- tating movement is imparted to the mold by means of the shaft 6, and the molten metal is then poured into the mold through the hopper 21 and its spout 22, the effect of the c entrifugal action being to cause the metal to seek the Walls of the mold and risethereon to an extent which is de endent uponthe speed of rotation ofthe mol Thus arelatively low rate of speed Will result in the formation of a cup-shaped ingot whose raised side portions ascend the walls of the mold' to a greater or less extent, while a relatively high rate of speed will cause all of the metal to seek the walls of the mold andwill resultin the production of a hollow or tubular ingot, as shown in Fig.' 2. As soon as the ingot is sufliciently set to retain the shape which has been imparted to it,the rotation of the shaft 6 is ar rested, the cross-head 12 is raised, the mold 11 is removed, an empty mold is inserted in A its lace, the cross-head 12 is again lowered,

an the operations before described are repeated.

An ingot-casting apparatus of the character described provides for the rapid. and effective formation of ing'ots of relatively small size, a single set of operating and rotating devices bein available for use in-connection with an .esired number of molds. It will be note that fan ingot-casting device such as .rec

2O from vertical,confinementA thereto said cap j that constituting the subject of my invention is essentially distinct from that class of rotating molds in which a core is employed, my

' -mold being ,coreless and the tubular 'formof 5 the ingot being due entirely to the centrifugal action ofthe rotating mold. Itis not necessary; therefore, in using myiimproved mold f to employ 'a -measured quantity of metal forl each ingot, since variation in the quantity of 1: metal y provided for each cast can only result' in 'varying thethickness ofthe ingot, and such' variation Within Wide limits is possible '-.be'cause of the absence of a core or other'rei v Str'ainin'g'inluence. x5 i `Having thus described my invention, I

claim anddesire to secure: by Letters Patent'.-

1. 'I he combination in 'ingoia-casting lappa;

, ratus, of a coreless'upright mold having a detachable cap in engagementwith it but .free

having a central opening and means independ- 'ht posts t having- -headver'ticallyguidedon saidfposts or colmeans for raising and lowering the said crosshead on its guides, substantially as specified.

3. The combination, in ingot-casting appa- 3 ratus, of a ixed'rame, having upright posts orrcolumns, a rotatable vertical shaft, a mold detachably mounted thereon, a cross-head vertically guided on said posts or columns, a hopper carried by said eross-he ad, and having a depending mold-illin spout, and a lever engaging said cross-hea and having a vertically-adjustable pivot or fulcrum, substantially as specified.

4. .The combination, in ingot-casting appa- 4 5 ratus, of a xedframe', having vertical posts or columns, a rotatable vertical shaft, a mold detachably mounted thereon, a cross-head guided l-on said postsA or columns, a hopper mounted upon said cross-head, and having a 5o depending mold-filling spout, a lever engaging'said cross-head, and a pair of bars ve tically -adjustable one-upon the other, one of said bars depending from the fixed lstructure and the other carrying thev flcrum of the le-A 5 5 ver substantially as specified.

In testimony whereof I have'signed'my name to this specification in the presence of two subscribing Witnesses.
